- ILLUMINATING DEVICE;

Application filed March 13, 1923'. Serial No. 24,781.

The invention relates to .an illuminating device foruse in connection wtlrtempernture indicators used on automobile, radiators for the purpose of indicating the temperature conditions of the water in the razdlZLiIQI...

An object of the invention is to provide an illuminating device :for a radiator temperature indicator which, at the :same time,

vides an intersection signal for the automobile.

Another object (of the invention is to pro- Mlidfi illuminating device for a radiator temperature indicator in which the source of serves as a par-king light, as an intersection signal and as a temperature indicating element illmnninating means.

A further object of the invention is to provide an illnminating device serving as an intersection signal and as :a parking light, of simple and inexpensive construction.

The invention possesses other advantageous features, some of which with the foregoing will he set forth at length in the following description, Where .Izshall outline in full, that form of the invention which I have selected lfior illustration in the drawings accompanying and forming part of the present specification. In said drawings I haveshown one specific form of illuminating device embodying my invention, but it is to be understood that I do not limit my- ;self to such form, since the invention, as set. forth the claims, may be embodied in .a lnralityofforms.

lteferring to said drawings: a

Figure l is a front elevation of the illumimating device of my invention attached to aradiator temperature indicator.

Fig. 2 is a vertical :section through the temperature indicator and the attached illuminating means.

Fig. .Sis a side view of the shell forming part of the illuminating means.

Fig. l is a perspective view looking into the shell.

Fig. 5 is a plan view of the holding band before being bent into shape.

The illuminating device of my invention is adapted primarily to be used in connection with a radiator temperature indicator, but it may be employed independently of the temperature indicator to serve as a parking light and an intersection signal. The

temperature indicator is usually enclosed-in a circular casing .2, having lenses or crystals 3 on opposite sides to protect the instrument. In equipping the radiator temperature instrument with the 1l1-um1na-t1n-g device of my invention, the crystal on the .far

side of the temperature indicator is removed :and the-device of my invention attached inv The device of my invention comprises :a-

metallic casing or shell 4 preferably circul-ar in form and having :a circular side wall 5., which terminates at its rear edge in an flaring flange 6 which is adapted to seat against the casing 52 of the ,temperature indicator and to be secured thereto by suitable means, such as screws .7. The front wall of the shell is provided with acirculwr aperture which is covered by a translucent lens 8, preferably of ground uncolored glass. The sidewall 5 of the shell is provided on each side with an aperture '9, preferably elongated in shape, and these apertures 9 are covered with translucent :elements preferably colored celluloid. The aperture 9 on the right is preferably covered with green celluloid and the aperture on the left is preferably covered with red celluloid so that, when a lamp is burning within the shell, va green light is indicated to the right of the vehicle and a red light is indicated to the left of the vehicle. "Since a vehicle approaching from the right has the right of way and the vehicle approaching from the .left must give way, these colored lights notify the drivers of approaching vehicles .at an intersection whether or not they or the vehicle carrying the signal has the right of Way. "There. is thus combined "one device means for ilh-iminating the radiator item- 'p'erature instrument, :a parking light and right of way signal. I

Arranged within the shell and preferably at the bottom thereof is a socket 14 adapted to receive the incandescent lamp 15. The socket is provided with a connector 17, extending through and insulated from the shell, to which an electric wire may be connected for the purpose of illuminating the device.

Unitary means are employed for holding in place the translucent lens 8 and the translucent strips of colored celluloid 12. This unitary device preferably comprises a metallic band 21 adapted to lie within the shell in contact with the circular side wall. The band is provided at; its end with projections 22 which fit behind the socket to hold the band in place. The band is further provided with apertures 23, which register with the apertures 9 in the side of the shell to permit the passage of light through the colored celluloid strips 12. These strips are clamped by the hand, between the band and the shell and are thereby held firmly in place. At its upper end the band is provided with an aperture 24, which seats over aprojection 25 formed in the upper portion of the shell to hold the band firmly in place at that point. Formed integral with the band and connected thereto by a neck 26, is a ring 27, which bears against the periphery of the lens 8, holding the lens in place. The band and ring are stamped from a single piece of thin metal, as shown in Fig. 5, and the ring is then bent upward to lie in a plane perpendicular to the plane of the band and the band is then fitted into the shell, with the ring bearing against the lens 8. Therefore the lens 8 and the colored celluloid strips are held in position by a single unitary means which is readily insertible into the shell.

I claim:

1. An illuminating device adapted to be attached to a temperature indicating instrument of an automobil radiator comprising a shell open at one end and having a side wall terminating in a flange at the open end adapted to seat against said instrument, at least two oppositely disposed translucent elements covering apertures in the side wall of the shell, a band extending around the inner periphery of said shell and adapted to retain both said translucent elements in position, and a lamp socket mounted within said shell.

2. An illuminating device comprising a shell having an opening in its front wall and a plurality of openings in its side wall, a translucent member covering the aperture in the front wall, translucent elements covering the apertures in the side wall, means for supporting a source of light within the shell and a single resilient integral member arranged within the shell for holding said translucent member and said translucent elements in position over their respective apertures.

3. An illuminating device comprising a shell having an opening in its front wall and a plurality of openings in its side wall, a translucent member covering the aperture in the front wall, translucent elements covering the apertures in the side wall, means for supporting a source of light within the shell, a band within the shell for holding said elements in position and an extension on said band for holding said member in position. 7

l. An illuminating device comprising a shell having an opening in its front wall and a plurality of openingsin its sidewall,

a translucent member covering the aperture in the front wall, translucent elements covering the apertures in the side wall, means for supporting a source of light within the shell, an annular member disposed within said shell and engaging said supporting means for holding said elements in position and a projection on said annular member for holding said translucent member in position.

5. An illuminating device comprising a shell having an opening in its front wall and a plurality of openings in its side wall, a translucent member covering the aperture in the front wall, translucent elements covering the apertures in the side wall, means for supporting a source of light within the shell, an apertured band for holding said elements in position and a ring integral with said band adapted to engage said translucent member. 7

6. In an illuminating device, a shell hav ing an apertured wall, a light transmitting member adapted to be positioned behind said wall, a lamp socket mountedwvithin said shell, and means including a resilient band engaging said lamp socket for retaining said member in position.

7. In an illuminating device comprising a shell having an open end wall, and an apertured side wall, a lens positioned behind said open end wall, a translucent screen positioned on the inner side of said sidewall to cover said aperture, a lamp socket mounted within said shell, and a single means engaging the socket for retaining said lens and said screen in their respective positions. v

In testimony whereof, I have hereunto setmy hand.
